I'm approaching 50, and I'll let you in on a little secret, we're not as tough as we act at this age. I had better senses, attention span, cognitive speed, reflexes, learning speed, joint mobility, stamina and a host of other useful, animal skills when I was 25 to 35 years old. Of course, I'm still "better with age" but that's basically experience at work, and 99% of what makes me better today than I was 20 years ago can be replaced by a team of experts at the other end of a radio link.
If I were the mission planner and I could have a ground crew of 200, but only 12 on the mission, I'd keep the grey hair down with their families, let 'em work ordinary 8 hour shifts and take normal vacations - you get better people that way, and you want the best people you can get. If you take the brightest, most talented and experienced person and caffeine fuel them for 18 hour shifts, you're still not getting better performance than you would from a team of 3 people who have figured out what's important to them in life and also happen to be experts in their field.
So, I'm saying, put the wunder-kind on the mission vehicle, support them with experienced ground crew. When the pioneers have established a reliable shirt-sleeve living and working environment that doesn't demand too much of the residents, then think about sending the old folks - they'll be able to contribute in great ways; but for pioneers you're better off working with people that don't have heavy family ties, arthritis, kidney stones and the occasional cancer that needs treatment.
I am also just a couple years short of the half-century mark. You are correct, I am not the man I was fifteen or twenty years ago.
But I think you miss my point. What good are fast reflexes and the exuberance of youth on a ten year mission to explore the Jupiter system? Most of the time would be spent waiting to arrive, and then manning consoles to run experiments. Nothing that requires super fast reflexes or the ability to stay awake for days at a time. It's also a good bet that radiation exposure would probably kill anyone attempting such a mission. Even if we make it clear that this would be a one-way trip, you'd have people lining up to make the journey. Again, I ask you -- "why waste all that potential?"
Construction, management and operation of a moon base would be another mission that would be ideally suited to older folks. Most of their time would be spent planning and managing, with power equipment doing all the heavy construction. No wunderkind required.
If we want to, say, explore Mars with a team of ten or so, or set up a colony, that would be the time for the youngsters, IMHO.
